The function that describes the graph is an exponential function
<h3>How to determine the function type?</h3>
From the graph, we have the following highlights:
- Initially, when x increases; y seem not to increase
- Then, x and y increase at the same time
- Finally, y increase and x seem not to increase
The above is the description of an exponential function
Hence, the function that describes the graph is an exponential function

Answer:
The axis of symmetry is x = -4
The function is negative over (-6, -2)
Answer:
15
Step-by-step explanation:
5 - 3[ 2 + (-5)] 2 - 8
Subtract 5 from 2 to get −3.
5 - 3 (-3) × 2 - 8
Multiply 3 and −3 to get −9.
5 - (-9 × 2) - 8
Multiply −9 and 2 to get −18.
5 - (-18) - 8
The opposite of −18 is 18.
5 + 18 - 8
Add 5 and 18 to get 23.
23 - 8
Subtract 8 from 23 to get 15.

Answer:
a. Narrower
b. Shifts left
c. Opens up
d. Shifts up
Step-by-step explanation:
The original quadratic equation is y = x²
The given quadratic equation is y = 5·(x + 4)² + 7
The given quadratic equation is of the form, f(x) = a·(x - h)² + k
a. A quadratic equation is narrower than the standard form when the coefficient is larger than the coefficient in the original equation
The quadratic coefficient is 5 > 1 in the original, therefore, the quadratic equation is <em>narrower</em>
b. Given that the given quadratic equation has positive 'a', and 'b', and h = -4, therefore, the axis of symmetry <em>shifts left</em>
c. The quadratic coefficient is positive, (a = 5), therefore, the quadratic equation <em>opens down</em>
d. The value of 'k' gives the vertical shift, therefore, the given quadratic equation with k = 7, <em>shifts up.</em>
Answer:
If you substitute (-1,2) meaning x and y
2=3(-1)-2
2=-3-2
2= -1
Step-by-step explanation:
he's incorrect since the solution does not equal 2 on both sides
